Description

TECHNICAL FIELD

[0001] The present application relates to the field of medical equipment, in particular to a fixed external kidney fistula tube and drainage container. BACKGROUND

[0002] Kidney fistulization is suitable for ureteral obstruction, kidney abscess, and ureteral obstruction caused by advanced bladder cancer, and is suitable for kidney stone removal surgery. Through kidney fistulization, the renal pelvis can be drained, the kidney function can be improved, and the infection of the renal pelvis and renal parenchyma can be reduced. Specifically, in the kidney fistulization surgery, an incision is made on the patient's body, a kidney fistula tube is inserted into the renal pelvis, and the kidney fistula tube is fixed in a kidney fistula port external manner after the kidney fistula tube is inserted into the renal pelvis. The incision of the renal pelvis is sutured. After the surgery, the kidney fistula tube is connected to the fistula bag, and the urine, pus, and blood in the patient's body are drained into the fistula bag through the kidney fistula tube.

[0003] In the existing kidney fistulization surgery, the kidney fistula tube can be kept in the patient's kidney fistula channel by suturing the incision, but a part of the kidney fistula tube will still hang outside the patient's body. In order to avoid the kidney fistula tube hanging outside the patient's body from shaking and causing the kidney fistula tube to fall off, the kidney fistula tube is usually fixed to the patient's waist skin by using adhesive tape, or the kidney fistula tube outside the body is knotted to reduce the shaking. If the adhesive tape is used for fixation, the adhesive area of the adhesive tape is small, and the kidney fistula tube and the adhesive tape may be separated from the patient's body due to slight movement of the patient, and multiple adhesive tapes are required to fix firmly, which not only is not firm enough, but also increases the workload of the doctor. If the fixation is only by knotting, it is difficult to avoid shaking, and the knotted part of the kidney fistula tube is easy to spread, which can easily cause the whole kidney fistula tube to separate from the patient.

[0004] Moreover, the existing fistula tube only relies on one drainage hole at the inner end to guide the body fluid to be discharged outside the body, and the patient is prone to blood coagulation after the surgery. The small blood clots are easy to block the drainage hole. If the fistula tube is not dredged or replaced, it may cause harm to the patient's body, and there is a certain hidden danger in use. Therefore, medical personnel need to check the delivery status of the fistula tube frequently, and promptly investigate the blockage status of the fistula tube, which increases the workload of the medical personnel.

Optionally, the length of the fluid inlet 1102 formed on the outer side of the drainage body 111 is greater than the length of the fluid inlet 1102 formed on the inner side of the drainage body 111, so that after the drainage body 111 bends towards the inner side of the drainage body 111 with the traction opening 1103, the fluid in the patient's body can flow out through the fluid inlet 1102 located on the outer side of the drainage body 111, so that the drainage body 111 in the bent state can still smoothly guide the fluid out.

[0093] It is worth noting that the specific number and implementation of the guide leaf 1112 and the fluid inlet 1102 are not limited, and the number of the guide leaf 1112 and the fluid inlet 1102 may be the same or different. The specific number and implementation of the guide leaf 1112 and the fluid inlet 1102 described in the text and shown in the accompanying drawings are merely examples and should not be construed as limiting the content and scope of the nephrostomy tube 100 of the present invention.

[0094] Furthermore, the drainage body 111 of the drainage body 110 has a traction opening 1104, wherein the traction opening 1104 is connected to the drainage channel 1101 of the drainage body 111, and the traction opening 1104 is formed at the inner end of the drainage body 110. During use, the nephrostomy tube 100 is inserted into the patient's stoma channel with the drainage body 111 facing the patient. The doctor can insert a linear traction device from the fluid outlet 1122 of the nephrostomy tube 100 into the fluid delivery channel 1121 of the delivery body 112, through the drainage channel 1101 and the traction channel 1103 of the drainage body 111, and out through the fluid inlet 1102 to reach the surgical site for subsequent surgical procedures.

[0095] Reference Figure 2 , Figures 9 to 11In some specific embodiments of the present invention, the drainage body 111 of the guiding device 110 is switchable between a bent state and a straight state. The drainage body 111 is in the bent state without external force. In the bent state, the drainage body 111 extends outwardly from the delivery body 112 in a curved manner, and the drainage body 111 is rolled up such that the traction opening 1104 approaches the inner wall. Further, the drainage body 111 of the drainage body 110 is elastic. The traction member entering the nephrostomy tube 100, after passing the drainage body 111, pulls the bent drainage body 111 towards a straight extension. The extension direction of the drainage body 111 is consistent with the extension direction of the delivery body 112, thereby switching the drainage body 111 of the guiding device 110 of the nephrostomy tube 100 from the bent state to the straight state.

[0096] After the traction member leaves the nephrostomy tube 100, the traction force from the traction member on the drainage body 111 of the guiding device 110 is removed, the drainage body 111 of the guiding device 110 releases elastic potential energy and returns to its initial state. That is, after the traction member is removed, the drainage body 111 returns from the straight state to the bent state and is held in the patient's body in a manner that maintains the bent state. The end of the drainage body 111 of the guiding device 110 is rolled up to avoid touching the patient's internal organs and causing adverse stimulation.

[0097] Reference Figure 6A and Figure 6B In some specific embodiments of the present invention, the drainage body 111 of the guiding device 110 of the nephrostomy tube 100 extends straight outward from the delivery body 112, i.e., it does not require traction from the traction member. The drainage body 111 of the guiding device 110 of the nephrostomy tube 100 always remains straight, and the extension directions of the drainage body 1111 and the delivery body 112 are always consistent. It is worth mentioning that the specific embodiments of the guiding device 110 of the nephrostomy tube 100 described in the accompanying drawings and text are merely examples and should not be construed as limiting the content and scope of the nephrostomy tube 100 of the present invention.

[0098] In a specific embodiment of the present invention, the fixation body 121 of the externally connectable fixation device 120 of the nephrostomy tube 100 includes a rigid retaining layer 1211 and a soft adhesive layer 1212, wherein the rigid retaining layer 1211 has a retaining surface 12102 and a holding surface 12104 opposite to the retaining surface 12102. The adhesive surface 12101 of the fixation body 121 is formed on the soft adhesive layer 1212, and the soft adhesive layer 1212 has a bonding surface 12105 opposite to the adhesive surface 12101. The soft adhesive surface 22 is disposed on the inner side of the rigid retaining layer 1211 such that the bonding surface 12105 is attached to the holding surface 12104 of the rigid retaining layer 1211. The external body 122 is disposed on the retaining surface 12102 of the rigid retaining layer 1211. For example, but not limited to, the rigid retaining layer 1211 and the soft adhesive layer 1212 are combined into one piece by hot pressing or adhesive bonding.

[0099] Preferably, the rigid retaining layer 1211 and the soft adhesive layer 1212 are an integral structure. For example, but not limited to, the rigid retaining layer 1211 and the soft adhesive layer 1212 are combined into one piece by a hot pressing process, which makes the structure strong, not easy to separate, and convenient for bearing weight in subsequent use.

[0100] Optionally, the rigid retaining layer 1211 and the flexible adhesive layer 1212 are separate structures. Specifically, both the bonding surface 12105 and the adhesive surface 12101 of the flexible adhesive layer 1212 are adhesive. Before use, the flexible adhesive layer 1212 and the rigid retaining layer 1211 are independent and separate from each other. During use, the flexible adhesive layer 1212 is adhered to the retaining surface 12104 of the rigid retaining layer 1211 with the bonding surface 12105 facing the rigid retaining layer 1211, thereby fixing the rigid retaining layer 1211 and the flexible adhesive layer 1212 together.

[0101] The rigid retaining layer 1211 has a higher hardness than the soft adhesive layer 1212. The fixing body 121 is adhered to the patient's body with the adhesive surface 12101 of the soft adhesive layer 1212 facing the patient's body. The soft adhesive layer 1212, which is in direct contact with the patient's body, is made of a soft material, which helps to prevent the fixing body 121 from scratching the patient's body when it rubs against the patient's body. For example, but not limited to, the soft adhesive layer 1212 is made of materials such as silicone or rubber. The rigid retaining layer 1211 is made of a harder material, which not only maintains the shape of the soft adhesive layer 1212 for easy direct adhesion, but also allows the fixing body 121 of the stoma tube 100 to be stably installed with the stoma bag 200 to receive the fluid discharged from the patient's body.

[0102] Preferably, the rigid retaining layer 1211 has a guiding channel, and the flexible adhesive layer 1212 has a flow channel. The flow channel of the flexible adhesive layer 1212 is connected to the guiding channel of the rigid retaining layer 1211, thereby forming the airflow channel 12103 of the fixing body 121. The air intake device 130 is disposed on the retaining surface 12102 of the rigid retaining layer 1211 such that the air intake channel 1301 is connected to the guiding channel of the rigid retaining layer 1211 of the fixing body 121.

[0103] The fixing body 121 further includes at least one covering layer 1213, wherein the covering layer 1213 is tearably covered over the adhesive surface 12101 of the soft adhesive layer 1212. The covering layer 1213 protects the adhesive surface 12101 of the soft adhesive layer 1212, preventing the adhesive surface 12101 from becoming less sticky and affecting its stability during subsequent use. In use, the covering layer 1213 and the adhesive surface 12101 of the soft adhesive layer 1212 are separated by tearing, exposing the adhesive surface 12101. The nephrostomy tube 100 is then inserted into the patient's body with the adhesive surface 12101 facing the patient's body. After the adhesive surface 12101 of the fixing body 121 is adhered to the patient's body, the nephrostomy tube 100 is stably held within the stoma channel in the patient's body.

[0104] In a specific embodiment of the present invention, the covering layer 1213 has a two-piece structure. Specifically, the covering layer 1213 includes two covering pieces 12131, each having a notch. The two covering pieces 12131 are adhered to the adhesive surface 12101 of the flexible adhesive layer 1212 such that the notches correspond to the conveying body 112 of the guiding device 110. The two covering pieces 12131 are respectively held on both sides of the conveying body 112, and completely cover the adhesive surface 12101 of the flexible adhesive layer 1212 to prevent contamination of the adhesive surface 12101. Preferably, the two covering pieces 12131 are held completely independently on both sides of the conveying body 112. Optionally, the two covering pieces 12131 are held on both sides of the conveying body 112 in a partially connected manner. For example, but not limited to, the cover sheet 12131 is made of plastic and has a smooth surface that is easy to tear.

[0105] Specifically, after the guiding device 110 of the nephrostomy tube 100 enters the patient's body, the two covering sheets 12131 are torn apart, and the adhesive surface 12101 of the covering sheet 12131 and the soft adhesive layer 1212 is separated, exposing the adhesive surface 12101, so that the fixing body 121 can be fixed to the patient's waist.

[0106] Optionally, the covering layer 1213 is a one-piece structure, i.e., two covering pieces 12131 are integrally formed. In use, the covering piece 12131 is first separated from the adhesive surface 12101 of the soft adhesive layer 1212, exposing the adhesive surface 12101. Then, the guiding device 110 of the nephrostomy tube 100 is held in the patient's body, and the fixing body 121 is fixed to the patient's waist by attaching the adhesive surface 12101 to the patient's waist. Those skilled in the art should understand that the specific implementation of the covering layer 1213 is merely an example and should not be construed as limiting the content and scope of the fixable nephrostomy tube 100 of the present invention.

[0107] Preferably, the width of the middle portion of the fixing body 121 is smaller than the width of the two ends of the fixing body 121, and the guiding device 110 is disposed in the middle portion of the fixing body 121. The shape of the fixing body 121 is adapted to the curvature of the patient's waist, which facilitates the secure adhesion of the adhesive surface 12101 of the fixing body 121 to the patient's body. Furthermore, when separating the nephrostomy tube 100 from the patient, the tearing force on the patient's stoma site can be reduced, alleviating pain.

[0108] Optionally, the fixing body 121 may be implemented as a regular shape such as a circle, rectangle, trapezoid, square, rhombus, ring, or other irregular shape. The specific implementation of the fixing body 121 is merely an example and should not be construed as a limitation on the content and scope of the nephrostomy tube 100 of the present invention.

[0109] In some specific embodiments of the present invention, the external body 122 of the externally connectable fixing device 120 of the nephrostomy tube 100 includes a support portion 1221 and an external portion 1222, wherein the external portion 1222 extends integrally outward from the support portion 1221, and the support portion 1221 is fixed to the fixing body 121. The connecting device 220 of the stoma bag 200 further includes an annular receiving interface holding portion 221 and a connecting portion 222, wherein the annular receiving interface holding portion 221 is fixed to the receiving interface 211 of the holding device 210, and the connecting portion 222 extends outward from the receiving interface holding portion 221. The connecting portion 222 of the connecting device 220 is detachably mounted to the external portion 1222 of the external body 122, so that the stoma bag 200 is detachably connected to the nephrostomy tube 100, and the fluid delivery channel 1121 of the delivery body 112 of the nephrostomy bag 100 is connected to the holding space 212 of the holding device 210 of the stoma bag 200.

[0110] Preferably, the supporting portion 1221 of the external body 122 has an annular structure, surrounding the fluid outlet 1122 of the nephrostomy tube 100. Furthermore, the hardness of the supporting portion 1221 of the external body 122 is greater than the hardness of the rigid retaining layer 1211 of the fixing body 121. This allows it to support the weight of the liquid contained in the stoma bag 200, and also disperses the force from the stoma bag 200, reducing the pulling effect of the stoma bag 200 and the contained liquid on the patient's wound, thus relieving pain. For example, but not limited to, the supporting portion 1221 of the external body 122 is fixed to the fixing body 121 by heat pressing or adhesive bonding. For example, but not limited to, the supporting portion 1221 of the external body 122 can be a circular ring, a square ring, a triangular ring, an elliptical ring, etc.

[0111] Reference Figure 3A and Figure 3BIn a specific embodiment of the present invention, the external portion 1222 of the external body 122 includes an extension arm 12221 and a limiting portion 12222. The extension arm 12221 extends vertically outward from the bearing portion 1221, and the limiting portion 12222 extends vertically outward from the extension arm 12221, forming a limiting groove 1220 between the extension arm 12221 and the limiting portion 12222. The connecting portion 222 of the connecting device 220 is a limiting protrusion extending outward from the receiving interface holding portion 221. The limiting protrusion is detachably embedded in the limiting groove 1220 of the external portion 1222, so that the stoma bag 200 is stably held outside the fixing body 121.

[0112] Reference Figure 7A and Figure 7B In a specific embodiment of the present invention, the external portion 1222 of the external body 122 is a limiting protrusion extending outward from the bearing portion 1221. The connecting portion 222 of the connecting device 220 includes an extension arm 2221 and an abutment portion 2222. The extension arm 2221 extends longitudinally outward from the receiving interface holding portion 221, and the abutment portion 2222 extends laterally outward from the extension arm 2221, forming a retaining groove 2220 between the receiving interface holding portion 221, the extension arm 2221, and the abutment portion 2222. The receiving portion 1221 of the external body 122 can be detachably embedded in the retaining groove 2220 so that the stoma bag 200 is stably held outside the fixing body 121.

[0113] Reference Figure 8A and Figure 8B In a specific embodiment of the present invention, the external connection portion 1222 of the external body 122 is detachably connected to the connecting portion 222 by means of a threaded connection. For example, the inner wall of the external body 122 is provided with an internal thread, and the connecting portion 222 is provided with an external thread that matches the internal thread. The connecting device 220 of the stoma bag 200 is detachably installed on the external body 122 of the externally connectable fixing device 120 by means of the external thread of the connecting portion 222 being connected to the internal thread.

[0114] Reference Figure 9In a specific embodiment of the present invention, the connecting portion 222 of the connecting device 220 of the stoma bag 200 includes at least two symmetrically arranged fastening claws 2223, wherein the fastening claw 2223 includes an elastic retaining portion 22231, a fastening arm 22232, and an abutting protrusion 22233, wherein the elastic retaining portion 22231 extends outwardly from the receiving interface retaining portion 221 in a flexible manner, the fastening arm 22232 extends outwardly vertically from the elastic retaining portion 22231, and the abutting protrusion 22233 extends inwardly obliquely from the fastening arm 22232, and a fastening groove 22230 is formed between the elastic retaining portion 22231, the fastening arm 22232, and the abutting protrusion 22233.

[0115] At least two of the elastic retaining portions 22231 of the latching claws 2223 can deform inward and approach the limiting portion 12222 of the external body 122 of the externally connectable fixing device 120. When the abutting protrusions 22233 of the two latching claws 2223 are in contact with the limiting portion 12222 of the external body 122, and the abutting protrusions 22233 enter the limiting groove 12220 between the limiting portion 12222 and the extension arm 12221, and the limiting portion 12222 of the external body 122 enters the latching groove 22230 of the latching claws 2223, the connecting device 220 of the stoma bag 200 is fastened to the externally connectable fixing device 120 of the nephrostomy tube 100. After the elastic retaining portion 22231 of the snap-fit ​​claw 2223 moves outward in a deformable manner, and the abutting protrusion 22233 leaves the limiting groove 1220, and the limiting portion 1222 of the external body 122 leaves the snap-fit ​​groove 22230, the connecting device 220 of the stoma bag 200 separates from the externally connectable fixing device 120 of the nephrostomy tube 100.

[0116] Preferably, four snap-fit ​​claws 2223 are provided, and the four snap-fit ​​claws 2223 are symmetrically arranged on the receiving interface holding portion 221. Optionally, three snap-fit ​​claws 2223 are provided.

[0117] It is worth noting that the specific embodiments of the external body 122 of the externally connectable fixing device 120 and the connecting device 220 are merely examples, and the specific structures of the external portion 1222 of the external body 122 and the connecting portion 222 of the connecting device 220 can be interchanged. For example, the external portion 1222 of the external body can be implemented to include at least two latching claws 2223, wherein the latching claws 2223 extend outward from the supporting portion 1221. The embodiments shown in the specification text and drawings should not be construed as limiting the content and scope of the nephrostomy tube 100 and the drainage container tool 1000 of the present invention.

[0118] In some specific embodiments of the present invention, the externally connectable fixing device 120 and the guiding device 110 of the nephrostomy tube 100 are an integral structure, that is, the fixing body 121 of the externally connectable fixing device 120 and the delivery body 112 of the guiding device 110 are fixedly connected, and the distance from the fluid inlet 1102 of the drainage body 111 of the guiding device 110 to the adhesive surface 12101 of the fixing body 121 is fixed and cannot be adjusted.

[0119] In one specific embodiment of the present invention, the fixing body 121 is integrally formed on the conveying body 112 of the drainage body 110. For example, the conveying body 112 of the drainage body 110 is held in a mold forming the soft adhesive layer 1212 of the fixing device 120, and the soft adhesive layer 1212 of the fixing body 121 is integrally formed. Then, the drainage body 120 with the soft adhesive layer 1212 is held in another mold forming the hard retaining layer 1211, and the hard retaining layer 1211 of the fixing body 121 is integrally formed on the soft adhesive layer 1212.

[0120] Reference Figure 5 In another specific embodiment of the present invention, the guiding device 110 further includes a connecting portion 114, wherein the connecting portion 114 extends outward from the outer periphery of the fluid outlet 1122 of the conveying body 112, and the connecting portion 114 is disposed on the fixing body 121 so that the guiding device 110 is fixed to the fixing body 121.

[0121] Optionally, the connecting portion 114 of the guiding device 110 is attached to the fixing body 121 in such a way that it is adhered to the connecting surface 12105 or the adhesive surface 12101 of the flexible adhesive layer 1212. For example, the flexible adhesive layer 1212 has a through hole, and the connecting portion 114 of the guiding device 110 is attached to the connecting surface 12105 of the flexible adhesive layer 1212 in such a way that the conveying body 112 is held in the through hole. Further, the flexible adhesive layer 1212 is attached to the connecting portion 114 of the guiding device 110 by means of adhesive bonding or hot pressing, and the adhesive surface 12101 faces the guiding device 110. Then, the rigid retaining layer 1211 is attached to the flexible adhesive layer 1212 by means of adhesive bonding or hot pressing.

[0122] Optionally, the connecting portion 114 of the guiding device 110 is attached to the fixing body 121 in such a way that it is adhered to the retaining surface 12102 or the holding surface 12104 of the rigid retaining layer 1211, and the guiding channel of the rigid retaining layer 1211 is connected to the airflow passage 1401 of the connecting portion 114. The soft adhesive layer 1212 is attached to the holding surface 12104 of the rigid retaining layer 1211 by adhesive bonding or hot pressing.

[0123] Optionally, the connecting portion 114 of the guiding device 110 is held at intervals between the retaining surface 12104 of the rigid retaining layer 1211 and the connecting surface 12105 of the soft adhesive layer 1212. For example, after the soft adhesive layer 1212 and the rigid retaining layer 1211 are bonded together by adhesive bonding or hot pressing, an assembly space is formed between the soft adhesive layer 1212 and the rigid retaining layer 1211, which communicates with the through hole of the soft adhesive layer 1212. The guiding device 110 is held on one side of the fixing body 121 such that the joint portion 114 is held in the assembly space. Glue or other molten adhesive material is poured into the assembly space. After the adhesive material solidifies, the adhesive material is filled between the bonding surface 12105 of the soft adhesive layer 1212 and the joint portion 114, and between the retaining surface 12104 of the rigid retaining layer 1211 and the joint portion 114.

[0124] In a specific embodiment of the present invention, the fixing body 121 further includes an extension 1214, wherein the extension 1214 has an extension channel 12141, wherein the extension 1214 extends outward from the holding surface 12102 of the fixing body 121, the fixing body 121 is disposed on the delivery body 112 such that the extension channel 12141 corresponds to the fluid outlet 112 of the delivery body 112 of the guiding device 110, and the extension channel 12141 of the extension 1214 of the fixing body 121 is connected to the fluid outlet 1122 of the delivery body 112. After the stoma bag 200 is installed on the external body 122 of the externally connectable fixing device 120 of the nephrostomy tube 100, the extension 1214 of the fixing body 121 of the nephrostomy tube 100 can be inserted into the receiving space 212 from the receiving interface 211 of the receiving body 210.

[0125] It is worth mentioning that in embodiments where the guiding device 110 and the externally connectable fixing device 120 of the nephrostomy tube 100 are integrated, when drainage is not required using the nephrostomy tube 100, medical personnel can observe the healing status of the surgical site through the fluid outlet 1122. The portion of the nephrostomy tube 100 that is additionally left outside the patient's body is relatively short. When the doctor observes the recovery status of the patient's surgical site through the channel of the nephrostomy tube 100, the nephrostomy tube 100 has minimal impact on the doctor's field of vision, facilitating clear observation of the patient's surgical site recovery.

[0126] Preferably, refer to Figure 5 The extension 1214 extends outward from the rigid retaining layer 1211, that is, the retaining surface 12102 of the rigid retaining layer 1211 extends outward to form the extension 1214.

[0127] Optionally, the conveying body 112 of the guiding device 110 is fixed to the fixing body 121 such that the fluid outlet 1122 is located outside the retaining surface 12102 of the fixing body 121, that is, the conveying body 112 of the guiding device 110 protrudes from the outer surface 12102 of the fixing body 121. The portion of the conveying body 112 of the guiding device 110 located outside the retaining surface 12102 of the fixing body 121 forms the extension 1214. Specifically, the fixing body 121 has a retaining channel 12106, wherein the conveying body 112 of the guiding device 110 is fixed to the retaining channel 12106 such that the fluid outlet 1122 is located outside the retaining surface 12102 of the fixing body 121. Thus, after the stoma bag 200 is installed on the external body 122 of the nephrostomy tube 100, the delivery body 112 of the guiding device 110 of the nephrostomy tube 100 can be inserted into the holding space 212 from the receiving interface 211 of the holding body 210 of the stoma bag 200. For example, the outer wall of the delivery body 112 of the guiding device 110 is firmly bonded to the inner wall of the fixing body 121 that defines the holding channel 12106 by an adhesive process.

[0128] Reference Figure 10 and Figure 11 In other embodiments of the present invention, the guiding device 110 and the externally connectable fixing device 120 of the nephrostomy tube 100 are separate structures. Specifically, the delivery body 112 of the guiding device 110 is movably held in the holding channel 12106 of the fixing body 121. The distance from the fluid inlet 1102 of the drainage body 111 of the guiding device 110 to the adhesive surface 12101 of the fixing body 121 can be adjusted, and the distance from the fluid inlet 1102 of the drainage body 111 to the adhesive surface 12101 of the fixing body 121 can be maintained at a fixed distance, which facilitates doctors to select different fixed distances according to the physical conditions of different patients, thereby improving the flexibility of the nephrostomy tube 100.

[0129] Specifically, the externally connectable fixation device 120 of the nephrostomy tube 100 further includes a limiting body 123, wherein the limiting body 123 is disposed on the fixation body 121, and the limiting body 123 is movably mounted on the delivery body 112 of the guide device 110. The limiting body 123 is switchable between a locked state and an active state, wherein in the active state, the limiting body 123 allows the delivery body 112 of the guide device 110 to move within the holding channel 12106 of the fixation body 121 to adjust the distance between the adhesive surface 12101 of the fixation body 121 and the fluid inlet 1102 of the guide device 110; in the locked state, the limiting body 123 can fix the delivery body 112 of the guide device 110 to the fixation body 121, restricting the movement of the delivery device 110 within the holding channel 12106 of the fixation body 121.

[0130] In this specific embodiment of the invention, the limiting body 123 includes an assembly 1231, an elastic member 1232, and a driving member 1233. The assembly 1231 has a receiving space 12310, the elastic member 1232 has a deformation channel 12320, and the driving member 1233 has a movable channel 12330. The assembly 1231 of the limiting body 123 is disposed on the fixing body 121 such that the receiving space 12310 is connected to the holding channel 1206 of the fixing body 121. The elastic member 1232 is disposed in the receiving space 12310 of the assembly 1231, and is held between the assembly 1231 and the driving member 1233. The deformation channel 12320 of the elastic member 1232 connects to the receiving space 12310 of the assembly 1231. The driving member 1233 is movably mounted on the assembly 1231, and the driving member 1233 can drive the elastic member 1232 to deform, so that the limiting body 123 can switch between the locked state and the active state.

[0131] Reference Figures 13A to 14When the limiting body 123 is in the active state, the distance between the driving member 1233 and the assembly 1231 is sufficient, the elastic member 1232 is not compressed, the elastic member 1232 does not deform and is in a natural state, and the conveying body 112 of the guiding device 110 is movably held in the holding channel 1206 of the fixed body 121, the accommodating space 12310 of the assembly 1231, the deformation channel 12320 of the elastic member 1232, and the active channel 12330 of the driving member 1233. At this time, the distance from the fluid inlet 1122 of the conveying body 112 of the guiding device 110 to the fixed body 121 can be adjusted. When the drive member 1233 and the assembly 1231 move relatively close, the drive member 1233 compresses the elastic member 1232, causing the elastic member 1232 to deform. The width of the deformation channel 12320 of the elastic member 1232 decreases, and the elastic member 1232 comes into close contact with the conveying body 112, compressing the conveying body 112. Further, under the compression of the drive member 1233, the upper end of the deformed elastic member 1232 is compressed into the space between the conveying body 112 and the drive member 1233, closely adhering to the inner walls of both the conveying body 112 and the drive member 1233. And, the lower end of the deformed elastic member 1232 is also compressed into the space between the conveying body 112 and the assembly 1231, closely adhering to the inner walls of both the conveying body 112 and the assembly 1233. Thus, the conveying body 112 of the guiding device 110 is fixed to the limiting body 123, and the distance between the fluid inlet 1102 of the guiding device 110 and the adhesive surface 12101 of the fixing body 121 is fixed.

[0132] More specifically, the driving member 1233 includes a holding portion 12331, a movable connecting portion 12332 extending downward from the holding portion 12331 at intervals, and a deformation driving portion 12333, wherein the deformation driving portion 12333 is located inside the movable connecting portion 12332, and the movable channel 12330 is formed in the deformation driving portion 12333. The mounting part 1231 includes a mounting portion 12311 and a receiving portion 12312, the receiving space 12310 passing through the receiving portion 12312 and the mounting portion 12311, the mounting portion 12311 being fixed to the fixing body 121, and the receiving portion 12312 extending upward integrally from the mounting portion 12311. The movable connecting portion 12332 of the driving member 1233 is movably mounted vertically to the receiving portion 12312 of the assembly 1231, such that the deformation driving portion 12333 is held in the receiving space 12310. The elastic member 1232 is held between the bottom of the receiving portion 12312 and the deformation driving portion 12333.

[0133] Preferably, the movable connecting portion 12332 of the driving member 1233 is movably mounted vertically to the receiving portion 12312 of the assembly 1231 via a threaded connection. For example, rotating the movable connecting portion 12332 of the driving member 1233 clockwise causes the driving member 1233 to move downward relative to the receiving portion 12312 of the assembly 1231. The deformation driving portion 12333 presses downward against the elastic member 1232, causing the elastic member 1232 to deform and press against the conveying body 112 of the guide device 110. The limiting body 123 is switched to the locked state, and the conveying body 112 of the guide device 110 is fixed to the fixing body 121. The guide device 110 cannot be displaced relative to the externally connectable fixing device 120. Furthermore, by rotating the movable connecting portion 12332 of the driving member 1233 counterclockwise, the driving member 1233 moves upward relative to the assembly 1231, the deformation driving portion 12333 and the elastic member 1232 separate, the elastic member 1232 releases its elastic potential energy and returns to its natural state, the limiting member 123 is switched to the active state, and the relative positions of the externally connectable fixing device 120 and the guiding device 110 can be adjusted.

[0134] In one specific embodiment of the present invention, the mounting portion 12311 of the assembly 1231 is fixed to the retaining surface 12102 of the rigid retaining layer 1211 of the fixing body 121. For example, the mounting portion 12311 of the assembly 1231 is firmly bonded to the retaining surface 12102 of the rigid retaining layer 1211 by adhesive bonding or hot pressing. Optionally, the mounting portion 12311 of the assembly 1231 is fixed between the rigid retaining layer 1211 and the soft adhesive layer 1212 of the fixing body 121.

[0135] Reference Figure 15A and Figure 15B In a specific embodiment of the present invention, the mounting portion 12311 of the fitting 1231 is detachably mounted to the fixing body 121. Thus, the limiting body 123 can be selectively mounted to the fixing body 121 according to usage requirements. Specifically, the externally connectable fixing device 120 further includes a mounting boss 124, wherein the mounting boss 124 extends outward from the rigid retaining layer 1211, and the mounting portion 12311 of the fitting 123 of the limiting body 123 is held on the outside of the fixing body 121 by being detachably mounted to the mounting boss 124. For example, but not limited to, the mounting portion 12311 is detachably mounted to the mounting boss 124 by means of threaded connection, interference fit, clearance fit, snap-fit ​​connection, etc.

[0136] Reference Appendix Figures 16 to 24 As shown, a fixed nephrostomy tube device with an external support component according to a preferred embodiment of the present invention is illustrated.

[0137] The fixed nephrostomy tube device with an external support component includes a nephrostomy tube 810, a fixing unit 820, and an external support component 830.

[0138] In this embodiment, the nephrostomy tube 810 has a drainage inlet 8101, a drainage outlet 8102, and a drainage channel 8103, wherein the drainage inlet 8101 and the drainage outlet 8102 are located at opposite ends and communicate with the drainage channel 8103. The nephrostomy tube 810 is adapted to be inserted into the body of a user, and the drainage inlet 8101 is located within the body of the user. The user may have a receiving channel formed, and the user may have a receiving opening formed on the body surface, the receiving opening being adapted to communicate with the receiving channel and the external environment. The nephrostomy tube 810 is adapted to enter the receiving channel through the receiving opening. Furthermore, the description uses a human body as an example. The nephrostomy tube 810 is provided with a marking line so that the nephrostomy tube 810 can be located under a detection device after being inserted into the body, facilitating the operator to control the insertion position and depth.

[0139] The nephrostomy tube 810 is adapted to be inserted from outside the user's body into the user's kidney. The external receiving component 830 is adapted to be placed outside the user's body to receive fluid from the nephrostomy tube 810. As the usage time increases, more and more fluid enters the external receiving component 830, which will cause the weight of the external receiving component 830 to increase.

[0140] The fixing unit 820 is adapted to be installed outside the body of the user. On the one hand, it fixes the nephrostomy tube 810 to prevent the nephrostomy tube 810 from falling out of the user's body. On the other hand, it fixes the external support to reduce the burden on the nephrostomy tube 810 placed by the fixing unit 820.

[0141] In detail, the fixing unit 820 includes a tube fixing part 821 and an integral fixing part 822. The integral fixing part 822 is adapted to be fixed to the body surface of the user, and the tube fixing part 821 is adapted to be fixed to the integral fixing part 822 so as to indirectly fix the nephrostomy tube 810 by means of the integral fixing part 822 fixed to the body surface of the user. Thus, assuming that when the external receiving component 830 is directly received by the nephrostomy tube 810, the fixing unit 820 can reduce the load on the nephrostomy function. On the one hand, it can reduce the probability of the nephrostomy tube 810 dislodging from the user's body, and on the other hand, it can reduce the pulling of the nephrostomy tube 810 caused by the shaking of the external receiving component 830. In other words, through the fixing unit 820, the impact that the external receiving component 830 might have on the nephrostomy tube 810 is transferred to the body surface of the user, rather than inside the body, thereby reducing the possibility of secondary damage to the user's internal channels, such as the stoma channel.

[0142] The external receiving component 830 can be disposed on the tube fixing part 821 or the body fixing part 822 of the fixing unit 820. The body fixing part of the fixing unit 820 is used to fix the tube fixing part 821. The two can be integrally formed or can be installed together later to form the fixing unit 820.

[0143] The tube fixing portion 821 is adapted to tightly bind the nephrostomy tube 810 to prevent the nephrostomy tube 810 from moving along the axial or radial direction of the tube fixing portion 821. The body fixing portion 822 is used to fix the tube fixing portion 821 to prevent the tube fixing portion 821 from moving relative to the body fixing portion 822. In this embodiment, the tube fixing portion 821 of the fixing unit 820 is configured to surround the nephrostomy tube 810 to fix the nephrostomy tube 810 at various positions around its periphery. Of course, it is understood that the arrangement of the relative positions of the tube fixing portion 821 and the nephrostomy tube 810 is not limited to this. The body fixing portion 822 of the fixing unit 820 is configured to surround the tube connection portion to fix the tube fixing portion 821 at various positions around its periphery. It is understandable that the arrangement of the relative positions of the tube fixing part 821 and the body fixing part 822 is not limited to this.

[0144] The body fixation part 822 is adapted to have a large cross-sectional area relative to the nephrostomy tube 810, so as to occupy a relatively large area of ​​the body surface of the user, thereby distributing the load from the nephrostomy tube 810 or the external support member 830 to the user through the body fixation part 822.

[0145] Furthermore, the external receiving component 830 can be disposed on the pipe fixing portion 821 or the body fixing portion 822 of the fixing unit 820. When the external receiving component 830 is disposed on the pipe fixing portion 821 of the fixing unit 820, the load brought by the external receiving component 830 is shared by the body fixing portion 822 arranged around the pipe fixing portion 821.

[0146] In this embodiment, the tube fixing part 821 and the body fixing part 822 of the fixing unit 820 are integrally connected. Therefore, the example described here is that the outer receiving part 830 is arranged in the tube fixing part 821 of the fixing unit 820. In fact, since the tube fixing part 821 and the body fixing part 822 are integrally formed, it is difficult to distinguish the specific boundary between the two. It can also be said that the outer receiving part 830 is arranged in the body fixing part 822 of the fixing unit 820.

[0147] In detail, the external receiving component 830 has a receiving cavity 8300 and a receiving interface 8301 communicating with the receiving cavity 8300. The nephrostomy tube 810 has the drainage outlet 8102. The receiving interface 8301 of the external receiving component 830 is adapted to be connected to the drainage outlet 8102 of the nephrostomy tube 810 to receive fluid from the nephrostomy tube 810. The external receiving component 830 may be, but is not limited to, a urine bag, a connecting tube, a detection device, etc. In this embodiment, the external receiving component 830 is described as a bag body.

[0148] The fixed nephrostomy tube device further includes a connecting unit 840, wherein the external receiving component 830 is fixed to the fixing unit 820 by the connecting unit 840, and the receiving interface 8301 of the external receiving component 830 is aligned with the drainage outlet 8102 of the nephrostomy tube 810. It is understood that the external receiving component 830 can be directly connected to the fixing unit 820, for example, through an integral connection.

[0149] In this embodiment, the connecting unit 840 includes a first connector 841 and a second connector 842. The first connector 841 is adapted to be disposed at the pipe fixing part 821 or the body fixing part 822 of the fixing unit 820. The second connector 842 is adapted to be disposed at the outer receiving part 830, for example, near the receiving interface 8301 of the outer receiving part 830, or the receiving interface 8301 is directly defined by the second connector 842. The first connector 841 or the second connector 842 may be integrally connected to the fixing unit 820 or the outer receiving part 830 beforehand, or they may be arranged separately on the fixing unit 820 and the outer receiving part 830 by installation later.

[0150] The first connector 841 and the second connector 842 can be detachably installed or integrally formed. In this embodiment, the first connector 841 and the second connector 842 are detachably connected, and the connection method can be screwed, snap-fit, etc. Those skilled in the art should understand that this is only an example and is not intended to limit the connection method of the first connector 841 and the second connector 842. Taking snap-fit ​​as an example, the first connector 841 forms a limiting groove 8410, and at least a portion of the second connector 842 is adapted to be snapped into the limiting groove 8410 of the first connector 841.

[0151] The connecting parts of the first connector 841 and the second connector 842 can be made of elastic materials, such as silicone, rubber, or other biosafety materials. When the second connector 842 is installed on the first connector 841, the elastic material allows either the second connector 842 or the first connector 841 to be slightly deformed and snapped onto the other, and after release, it can naturally recover its deformation to make the connection between the two more secure.

[0152] Furthermore, the connecting unit 840 includes a connecting auxiliary member 843, which is used to lock the first connecting member 841 and the second connecting member 842, so that the connection between the first connecting member 841 and the second connecting member 842 is tighter. The connecting auxiliary member 843 is suitable to be made of a rigid material, relative to the materials of the first connecting member 841 and the second connecting member 842, so that the connecting auxiliary member 843 can play a fastening role after the first connecting member 841 is sleeved on the second connecting member 842. Specifically, the second connecting member 842 has a positioning groove 8420, which is located in the limiting groove 8410 of the first connecting member 841. When the connecting auxiliary member 843 is installed to secure the first connecting member 841 and the second connecting member 842, at least a portion of the connecting auxiliary member 843 is adapted to be installed in the positioning groove 8420 of the second connecting member 842 to be confined within the second connecting member 842 and to secure the first connecting member 841 and the second connecting member 842. The connecting auxiliary member 843 binds the second connecting member 842 and the first connecting member 841 from the outside inwards so that the second connecting member 842 and the first connecting member 841 fit tightly, thereby preventing fluid from seeping out from the location of the second connecting member 842 and the first connecting member 841.

[0153] The contour of the limiting groove 8410 of the first connector 841 is set to be similar to the contour of the second connector 842 so that the second connector 842 can fit tightly against the first connector 841 at the limiting groove 8410 position. The contour of the positioning groove 8420 of the second connector 842 is set to be similar to the contour of the connecting auxiliary member 843 so that the connecting auxiliary member 843 can fit tightly against the second connector 842 at the positioning groove 8420 position.

[0154] The number of limiting grooves 8410 can be two, three, or more, and the number of positioning grooves 8420 can be two, three, or more. It is understood that the limiting grooves 8410 and the positioning grooves 8420 can be formed on the periphery of the first connector 841 and the second connector 842, or on the top or bottom side of the first connector 841 and the second connector 842, so that the first connector 841 and the second connector 842 can be more tightly joined.

[0155] In this embodiment, the first connector 841 and the second connector 842 are respectively implemented as circular, so that during the installation of the first connector 841 and the second connector 842, the first connector 841 and the second connector 842 do not need to be aligned to complete the installation, and their relative positions can be adjusted as needed after installation. Further, the connecting auxiliary member 843 is implemented as circular to lock the first connector 841 and the second connector 842 at various positions along their circular outlines. It is understood that the contact between the connecting auxiliary member 843 and the first connector 841 and the second connector 842 can be intermittent; for example, the connecting auxiliary member 843 may only fasten the connection between the first connector 841 and the second connector 842 at a few preset positions. The shape of the connecting auxiliary member 843 can be similar to or different from that of the first connector 841 and the second connector 842.

[0156] It is understood that the shapes of the first connector 841, the second connector 842, and the connecting auxiliary member 843 may be, but are not limited to, triangles, rectangles, ellipses, polygons, etc.

[0157] Furthermore, the connecting auxiliary member 843 has a first end 8431, a second end 8432, and a connection port 8430 formed between the first end 8431 and the second end 8432. The first end 8431 and the second end 8432 of the connecting auxiliary member 843 can be opened to form the connection port 8430, and can also be closed to form a ring structure. The connecting auxiliary member 843 has an open state and a closed state, and the connecting auxiliary member 843 can be operated to switch between the open state and the closed state. When the connecting auxiliary member 843 is in the open state, the connection port 8430 is formed and can be expanded by controlling the distance between the first end 8431 and the second end 8432, so that the connecting auxiliary member 843 can be easily fitted onto the first connecting member 841 and the second connecting member 842 through the connection port 8430. When the connecting auxiliary member 843 is in the closed state, the connecting port 8430 is closed, and the first end 8431 and the second end 8432 are locked so that the connecting auxiliary member 843 secures the first connecting member 841 and the second connecting member 842. The first end 8431 and the second end 8432 of the connecting auxiliary member 843 are configured to be detachably connected, for example, by snap-fit ​​connection, adhesive bonding, or screw connection. Of course, those skilled in the art will understand that the connection method of the first connecting member 841 and the second connecting member 842 here is only an example, and it can be modified and extended based on this principle.

[0158] Furthermore, the first connector 841 of the connecting unit 840 is disposed on the tube fixing portion 821 of the fixing unit 820, so that the fixing unit 820 supports the external receiving component 830. It is understood that the positions of the first connector 841 and the second connector 842 can be interchanged.

[0159] The fixing unit 820 is used not only to support the external receiving component 830, but also to fix the nephrostomy tube 810. Specifically, the fixing unit 820 includes a tube fixing part 821 and a body fixing part 822. The body fixing part 822 is adapted to be connected to the tube fixing part 821, and the tube fixing part 821 is adapted to be fixedly connected to the body fixing part 822. The body fixing part 822 is adapted to be fixedly connected to the body surface of the user, so that the nephrostomy tube 810 is fixed in a predetermined position by means of the tube fixing part 821 of the fixing unit 820.

[0160] In other words, unlike the conventional method of directly fixing the nephrostomy tube 810 by means of the skin forming the accommodating opening, in this embodiment, the nephrostomy tube 810 is fixed by the tube fixing part 821 of the fixing unit 820, the tube fixing part 821 is fixed by the body fixing part 822, and the body fixing part 822 is fixed to the body surface of the user, so that the nephrostomy tube 810 is fixed to the body surface of the user by means of the fixing unit 820.

[0161] In this way, during the use of the nephrostomy tube 810, on the one hand, it is not necessary to tighten the accommodating opening of the user to fix the nephrostomy tube 810; on the other hand, when the nephrostomy tube 810 is pulled out or is subjected to a large external force that tends to detach from the accommodating channel of the user, the part bearing the force from the nephrostomy tube 810 is concentrated on the fixation unit 820. For the user, the body surface of the body fixation part 822 in contact with the fixation unit 820 may bear a large force, while the accommodating opening of the user is not the main force bearing force. When the accommodating opening is a wound, the probability of the accommodating opening being injured again is reduced.

[0162] It is also worth noting that, because the fixed indwelling device exerts less pressure on the accommodating opening of the user when subjected to external forces, the fixed indwelling device can withstand a large load without causing significant impact on the accommodating channel or the body tissue near the accommodating opening of the user.

[0163] Furthermore, because the pressure borne by the fixed indwelling device is distributed to the user's body surface, if the exposed nephrostomy tube 810 is pulled during the user's activities, the force can be dispersed to the user's body surface rather than concentrated at the receiving opening, thus avoiding pulling on the muscles and tissues at that location. From another perspective, the user's range of motion can be expanded without constantly worrying about their movements immediately pulling on the receiving opening.

[0164] Furthermore, the tube fixing portion 821 of the fixing unit 820 is configured to extend outward from the periphery of the nephrostomy tube 810, and the nephrostomy tube 810 is fixedly held in the tube fixing portion 821. The body fixing portion 822 is configured to extend outward from the periphery of the tube fixing portion 821, and the tube fixing portion 821 is surrounded by the body fixing portion 822. In this way, the tube fixing portion 821 can be more securely supported in the fixing unit 820. Once the body fixing portion 822 of the fixing unit 820 is fixed to the skin surface of the user, the position of the nephrostomy tube 810 fixedly connected to the tube fixing portion 821 is fixed because the body fixing portion 822 is fixedly connected to the tube fixing portion 821.

[0165] Furthermore, in this embodiment, the tube fixing part 821 and the body fixing part 822 of the fixing unit 820 are designed to be integrally formed, so that the connection between the tube fixing part 821 and the body fixing part 822 of the fixing unit 820 is more stable.

[0166] Furthermore, the structure and shape of the fixing unit 820 are designed to make the entire fixed placement device easy to install and convenient for the user's movement during use.

[0167] For more details, please refer to the appendix. Figure 7A To be continued Figure 9 The fixing unit 820 has two end portions 8221 extending along the length direction of the fixing unit 820 and two opposing inwardly recessed portions 8222 extending between the two end portions 8221. The entire fixing unit 820 is designed to resemble a saddle shape or a butterfly shape.

[0168] When the fixed indwelling device is installed on the user, the fixing unit 820 is attached to the user's skin surface. In particular, in this embodiment, the fixing unit 820 is attached to the user's waist.

[0169] The two inwardly recessed recesses 8222 of the fixing unit 820 are located in the vertical direction, respectively. When the user bends over towards the side where the fixing unit 820 is installed, due to the presence of the two recesses 8222 of the fixing unit 820, the skin near the fixing unit 820 of the user will not have too much contact with the fixing unit 820 itself when squeezed, so as not to cause discomfort to the user.

[0170] In other words, the body fixing part 822 of the fixing unit 820 has an outer periphery 8223, which has an upper periphery 82231, a lower periphery 82232, a left periphery 82233, and a right periphery 82234. The upper periphery 82231 and the lower periphery 82232 are arranged opposite to each other, and the left periphery 82233 and the right periphery 82234 are arranged opposite to each other. Furthermore, the upper periphery 82231 and the lower periphery 82232 are designed to be concave inward. The cross-section of the fixing unit 820 at the waist position is designed to be at its smallest overall cross-sectional size, while the cross-sections on the front and rear surfaces of the body are designed to be larger than those at the waist position. This reduces the contact between the fixed indwelling device and the waist skin at the waist position, facilitating the user's movement. Furthermore, because the fixing unit 820 of the fixed indwelling device is relatively small at the waist position, installation is also more convenient.

[0171] The connection between each end 8221 and the recess 8222 of the fixing unit 820 is designed with rounded corners to improve the comfort of the fixing unit 820 when it is installed on the skin.

[0172] Furthermore, at least a portion of the fixing unit 820 may be made of a flexible material, which is suitable for installation to conform to the curves of the human skin surface and can improve the comfort of the user with the fixed indwelling device installed.

[0173] The fixing unit 820 has an attachment surface 8224, which may be formed on the body fixing part 822 or on the body fixing part 822 and the tube fixing part 821. The attachment surface 8224 is disposed on the side facing the nephrostomy tube 810, and the attachment surface 8224 is adapted to attach to the skin surface of the user.

[0174] The fixing unit 820 includes a substrate layer 8225, an adhesive layer 8226, and a peelable layer 8227, wherein the adhesive layer 8226 is located between the substrate layer 8225 and the peelable layer 8227. The substrate layer 8225 is made of a flexible material, the adhesive layer 8226 is attached to the substrate layer 8225 to adhere to the skin surface of the user, and the peelable layer 8227 covers the surface of the adhesive layer 8226 so that it can be peeled off to expose the adhesive layer 8226 when the fixing unit 820 is in use. The adhesive surface may form at least a portion of the attachment surface 8224. In this embodiment, the entire attachment surface 8224 is configured to adhere to the skin surface of the user by adhesive means. The body fixing portion 822 may consist only of the substrate layer 8225, or only of the substrate layer 8225 and the adhesive layer 8226. That is, the adhesion surface 8224 may be located on the substrate layer 8225 or the adhesive layer 8226. The substrate layer 8225 or the adhesive layer 8226 can be attached to the user object by the material properties of the material itself, or by a medium, such as a biosafety adhesive. It is understood that the types of media mentioned are merely illustrative and do not imply limitation of the invention.

[0175] The tube fixing portion 821 and the body fixing portion 822 of the fixing unit 820 respectively include at least a portion of the substrate layer 8225, at least a portion of the adhesive layer 8226, and at least a portion of the peelable layer 8227. The nephrostomy tube 810 is disposed on the tube fixing portion 821, and optionally, the nephrostomy tube 810 can be integrally formed on at least a portion of the tube fixing portion 821, or the nephrostomy tube 810 and the tube fixing portion 821 can be formed separately.

[0176] For ease of installation, the peelable layer 8227 is designed in two parts: a first peelable layer 82271 and a second peelable layer 82272. The peelable layer 8227 includes the first peelable layer 82271, the second peelable layer 82272, and has a separator line 82273 and a through hole 82270. The separator line 82273 passes through the through hole 82270, which allows the nephrostomy tube 810 to pass through. The nephrostomy tube 810 is located in the direction of the extension of the separator line 82273, and the separator line 82273 separates the first peelable layer 82271 and the second peelable layer 82272. The nephrostomy tube 810 can be located at the junction of the first peelable layer 82271 and the second peelable layer 82272.

[0177] When the fixed indwelling device is in use, the nephrostomy tube 810 first needs to be aligned with the receiving opening, and then the nephrostomy tube 810 is pushed into the receiving channel. It is understood that the nephrostomy tube 810 can enter the receiving channel with the assistance of some auxiliary guiding tools, especially when the nephrostomy tube 810 is made of a soft material and lacks a certain rigidity.

[0178] After the nephrostomy tube 810 has entered the receiving channel to a certain depth, the fixing unit 820 still maintains a certain distance from the user. At this point, the first portion 82271 or the second portion 82272 of the peelable layer 8227 can be peeled off to expose the corresponding portion of the adhesive layer 8226. In this embodiment, the dividing line 82273 divides the peelable layer in two, and the entire fixing unit 820 is arranged symmetrically with respect to the dividing line 82273.

[0179] After one half of the adhesive layer 8226 of the fixing unit 820 is exposed, the exposed portion can be pushed forward directly to adhere to the skin surface of the user, and then the other half of the peelable layer 8227 can be peeled off, and the remaining exposed portion of the adhesive layer 8226 can be adhered to the skin surface of the user.

[0180] Using the above method, the peelable layer 8227 is divided into two, reducing the area that the operator needs to bond at one time during operation, thus facilitating bonding.

[0181] Additionally, it is worth noting that the dividing line 82273 is configured to extend between the two recesses 8222, that is, the dividing line 82273 extends in the width direction of the fixing unit 820. The two ends 8221 are configured to be enlarged relative to the position of the recesses 8222, and the connection between the ends 8221 and the recesses 8222 is rounded to facilitate operation during the bonding process.

[0182] In another embodiment of the invention, the number of the dividing lines 82273 may be two, extending between the two recesses 8222 respectively, to divide the peelable layer 8227 into three parts: a first peelable layer 82271, a second peelable layer 82272, and a third peelable layer, wherein the second peelable layer 82272 is located between the first peelable layer 82271 and the third peelable layer, and the nephrostomy tube 810 is arranged in the second peelable layer 82272, and the through hole 82270 is formed in the second peelable layer 82272.

[0183] During use, the second peelable layer 82272 can be removed first. For example, it can be removed through the nephrostomy tube 810, or a cut can be made in the second peelable layer 82272 to allow it to detach from the connection between the nephrostomy tube 810 and the fixing unit 820.

[0184] When the nephrostomy tube 810 is guided to the intended depth on the user, the operator can directly attach the adhesive layer 8226 corresponding to the second peelable layer 82272 to the skin surface of the user, that is, the skin surface near the receiving opening of the nephrostomy tube 810, thereby fixing the nephrostomy tube 810.

[0185] However, the operator can remove either the first peelable layer 82271 or the third peelable layer to attach the two ends 8221 to the skin surface of the user, thereby fixing the tube fixing part 821 of the nephrostomy tube 810 to the skin surface of the user through the body fixing part 822.

[0186] In addition, in this way, the tube fixing part 821 of fixing the nephrostomy tube 810 can be directly fixed to the skin surface of the user, such as the waist, while the fixed indwelling device is being pushed toward the user. The body fixing part 822 of fixing the tube fixing part 821 can be adjusted and fixed after the tube fixing part 821 according to the skin curve of the human body.

[0187] Furthermore, it can be understood that in this embodiment, the tube fixing part 821 and the body fixing part 822 of the fixing unit 820 are together fixed to the body surface of the user by adhesive bonding. The tube fixing part 821 is fixed to the nephrostomy tube 810 by integral connection, fixed to the body fixing part 822 by integral connection, and fixed to the body surface of the user by adhesive bonding. In this way, the fixation of the nephrostomy tube 810 of the fixed indwelling device is very stable, and the nephrostomy tube 810 is difficult to move forward, backward, or left and right in the receiving channel relative to the receiving opening, while keeping the fixing unit 820 and the skin surface of the user fixed.

[0188] It is understood that the tube fixing part 821 does not necessarily need to be fixed to the body surface of the user along with the body fixing part 822 of the fixing unit 820; its main function is to fix the nephrostomy tube 810. Therefore, according to one embodiment of the present invention, the nephrostomy tube 810 is fixed to the tube fixing part 821, the tube fixing part 821 is fixed to the body fixing part 822, the body fixing part 822 is fixed to the body surface of the user, and the tube fixing part 821 is not fixed to the body surface of the user.

[0189] It is understood that the tube fixing part 821 does not necessarily have to use an integral fixing method to fix the nephrostomy tube 810. Its fixing method can be various, such as snap-fit ​​fixing connection, spiral fixing connection, etc.

[0190] Furthermore, in this embodiment, the tube fixing part 821 is integrally surrounded by the nephrostomy tube 810 and holds the nephrostomy tube 810 to prevent the nephrostomy tube 810 from moving forward or backward or left or right relative to the receiving opening.

[0191] In this embodiment, each part of the fixing unit 820 is configured to have a uniform thickness. For example, each position of the body fixing part 822 and the tube fixing part 821 of the fixing unit 820 is configured to have a uniform thickness.

[0192] The fixation unit 820 has an inner surface and an outer surface, which are disposed opposite to each other. An attachment surface 8224 is formed on the inner surface, which is adapted to contact the skin surface of the user. The inner and outer surfaces can each be a plane, so that after the fixation unit 820 is attached to the user, the user will not experience discomfort due to the presence of the fixation unit 820 and the nephrostomy tube 810.

[0193] Furthermore, the substrate layer 8225 of the fixing unit 820 can be a stretchable substrate such as a membrane, nonwoven fabric, cotton fabric, knitted fabric, or a laminated composite of nonwoven fabric and membrane. Examples of materials that can be used as these substrates include, for example, polyethylene, polypropylene, polyethylene terephthalate, polyethylene terephthalate, polyethylene naphthalate, polystyrene, polyamide, polyolefin, nylon, cotton, sizing agent, acetate rayon, rayon, rayon / polyethylene terephthalate composite, polyacrylonitrile, polyvinyl alcohol, acrylic polyurethane, ester polyurethane, ether polyurethane, styrene-isoprene-styrene copolymer, styrene-butadiene-styrene copolymer, styrene-ethylene-propylene-styrene copolymer, and ethylene-vinyl acetate copolymer.

[0194] The substrate layer 8225 can be mixed with various strength control agents, brightening agents such as inorganic powders, dyes, pigments, etc., which are widely used in this technical field. Furthermore, the substrate layer 8225 can also be manufactured using any of the following methods: uniaxial stretching, biaxial stretching, or non-stretching. Moreover, the substrate layer 8225 can be not only a single-layer structure, but also a multi-layer structure formed by overlapping multiple layers of different or the same type.

[0195] The thickness of the substrate layer 8225 is not particularly limited, but it may be less than μm to facilitate elasticity and moisture permeability, and may be greater than μm to facilitate strength.

[0196] Furthermore, the adhesive layer 8226 can be made of rubber-based adhesives, acrylic adhesives, silicone adhesives, hydrocolloids, etc. When the fixed indwelling device is adhered to the skin surface of the user, the adhesive layer 8226 is located between the user and the substrate layer 8225. Considering the tightness and adhesion between the substrate layer 8225 and the adhesive layer 8226, isocyanate-based crosslinking agents, metal chelate-based crosslinking agents, tackifiers, etc., can be appropriately added to the manufacturing material of the adhesive layer 8226. Preferably, the molecular weight of the adhesive component forming the adhesive layer 8226 is set to be relatively high to inhibit the penetration of the adhesive into the skin. Considering moisture permeability, the adhesive layer 8226 should not be made too thick, for example, it can be made below μm; considering adhesive performance, the adhesive layer 8226 should not be made too thin, for example, it can be made above μm. It is understood that the adhesive layer 8226 may be configured to completely cover the substrate layer 8225, or it may be designed to have regular patterns such as dots or stripes or random patterns arranged on the substrate layer 8225.

[0197] Furthermore, the peelable layer 8227 can be designed to be paper or plastic.

[0198] In this embodiment, the nephrostomy tube 810 includes a nephrostomy tube body 811, which forms the drainage channel 8103, the drainage inlet 8101, and the drainage outlet 8102. The nephrostomy tube body 811 has a starting end 8111 and an opposing end 8112, with the drainage inlet 8101 located at the starting end 8111 and the drainage outlet 8102 located at the end 8112. The drainage channel 8103 extends between the starting end 8111 and the end 8112 of the nephrostomy tube body 811. The end 8112 of the nephrostomy tube body 811 can be disposed in the fixing unit 820 and located in the tube fixing portion 821 of the fixing unit 820.

[0199] The fixing unit 820 may have a fixing opening 8201, which is located at the tube fixing portion 821 of the fixing unit 820. The drainage outlet 8102 of the nephrostomy tube body 811 of the nephrostomy tube 810 communicates with the fixing opening 8201 of the fixing unit 820, so that fluid from the body enters the drainage channel 8103 through the drainage inlet 8101 of the nephrostomy tube body 811, and is then transferred to the outside through the fixing opening 8201 of the fixing unit 820. It is understood that the drainage opening 8101 of the nephrostomy tube 810 and the fixing opening 8201 of the fixing unit 820 may be the same. The end portion 8112 of the nephrostomy tube body 811 of the nephrostomy tube 810 extends to the position of the fixing opening 8201 of the fixing unit 820. It is understandable that the nephrostomy tube body 811 of the nephrostomy tube 810 can pass through the fixing opening 8201 of the fixing unit 820 and continue to extend outward. In other words, the nephrostomy tube body 811 of the nephrostomy tube 810 can extend to both sides of the fixing unit 820, and the drainage outlet 8102 of the nephrostomy tube 810 and the fixing opening 8201 of the fixing unit 820 maintain a large distance. Those skilled in the art can arrange the relative positional relationship between the drainage outlet 8102 of the nephrostomy tube 810 and the fixing opening 8201 of the fixing unit 820 according to requirements.

[0200] Furthermore, the nephrostomy tube 810 includes an air bladder 813, wherein the air bladder 813 is disposed on the nephrostomy tube body 811 of the nephrostomy tube 810 and is arranged adjacent to the starting end 8111 of the nephrostomy tube body 811. The air bladder 813 can be inflated to increase its volume, which on the one hand can play a role in compressing and stopping bleeding, and on the other hand, the inflated air bladder 813 can prevent the nephrostomy tube body 811 from dislodging outward. In other words, the nephrostomy tube body 811 can be fixed by means of both the air bladder 813 and the fixing unit 820, achieving double fixation to reduce the possibility of the nephrostomy tube body 811 dislodging.

[0201] The nephrostomy tube 810 has a fluid channel 8104, wherein the fluid channel 8104 is adapted to communicate with the balloon 813 for inflating or deflating the balloon 813. The fluid channel 8104 can be arranged along the length of the nephrostomy tube body 811, and can be arranged side by side with the channel. The nephrostomy tube 810 forms a fluid outlet 8105, the fluid outlet 8105 is adapted to communicate with the fluid channel 8104, and the balloon 813 and the fluid outlet 8105 are respectively located at both ends of the fluid channel 8104. Fluid can be inflated into the balloon 813 through the fluid outlet 8105 from the fluid channel 8104, so as to inflate the balloon 813, or it can flow to the outside through the fluid outlet 8105, so as to deflate the balloon 813. It is worth noting that the fluid inflated into the balloon 813 can be gas or liquid, whichever is required.

[0202] The nephrostomy tube body 811 can be made of a soft material, such as rubber or silicone. The airbag 813 can also be made of a soft material, such as rubber or silicone. The nephrostomy tube body 811 and the airbag 813 can be integrally molded.

[0203] Furthermore, when the nephrostomy tube 810 of the fixed indwelling device is inserted into a preset position in the body and the fixing unit 820 is fixed to the body surface, the fluid outlet 8105 is exposed to facilitate user operation, such as inflating the airbag 813 by filling it with air through the fluid outlet 8105.

[0204] In this embodiment, for ease of operation, the nephrostomy tube 810 further includes a delivery tube 813, which is connected to the fluid channel 8104 so that the air bag 813 can be inflated through the delivery tube 813.

[0205] The delivery tube 813 is arranged in the fixation unit 820 and communicates with the airbag 813 via the fixation unit 820. In other words, at least a portion of the fluid channel 8104 can be formed in the fixation unit 820. In this way, the user is not affected by the fixation opening 8201 of the fixation unit 820 when operating the delivery tube 813. In this embodiment, the delivery tube 813 is arranged at the periphery of the fixation unit 820. The fixation between the fixation unit 820 and the patient does not affect the delivery tube 813.

[0206] Further, in this embodiment, the nephrostomy tube 810 has at least one drainage groove 8106, and the number of drainage grooves 8106 can be one, two, three, four, or more. The drainage inlet is arranged close to the starting end 8111 of the nephrostomy tube 810, relative to the ending end 8112. Each drainage groove 8106 is connected to the drainage inlet, and the drainage groove 8106 is configured to extend towards the starting end 8111 from the location of the drainage inlet. The drainage groove 8106 is openly disposed on the surface of the nephrostomy tube 810.

[0207] This embodiment uses six drainage channels 8106 as an example for illustration. The nephrostomy tube 810 includes a front section 814 and a rear section 815. The front section 814 includes a support column 8141 and at least two partition walls 8142. The drainage channels 8106 are formed between two adjacent partition walls 8142, and the partition walls 8142 extend outward from the periphery of the support column 8141. The rear section 815 extends from the front section 814. The drainage inlet is located at the connection between the front section 814 and the rear section 815. Preferably, the cross-section of the partition wall 8142 is T-shaped and has an arc-shaped side to facilitate the insertion of the nephrostomy tube 810.

[0208] The nephrostomy tube 810 has a guide channel 8107 that extends throughly from the starting end 8111 to the ending end 8112. The guide channel 8107 is adapted to be fitted with a guide wire or other guide to guide the flexible nephrostomy tube 810 into the intended position. At least a portion of the guide channel 8107 of the nephrostomy tube 810 is formed in the anterior segment 814 and at least a portion is formed in the posterior segment 815. The drainage channel 8103 of the nephrostomy tube 810 is formed in the posterior segment 815, and the drainage groove 8106 communicates with the drainage channel 8103 via the drainage inlet 8101. At the posterior segment 815, the drainage channel 8103 forms at least a portion of the guide channel 8107. In other words, at least a portion of the drainage channel 8103 and the guide channel 8107 are shared.

[0209] In this embodiment, there are six drainage channels 8106 and six drainage inlets 8101, with each drainage channel 8106 corresponding to one drainage inlet 8101. There are six partition walls 8142 to separate the six drainage channels 8106. At least a portion of the guide channel 8107 is formed in the support column 8141 of the pipe front section 814.

[0210] Compared to a traditional nephrostomy tube 810, the nephrostomy tube 810 provided in this embodiment offers multiple drainage inlets 8101 for fluid entry into the nephrostomy tube 810, thereby reducing the probability of one drainage inlet 8101 becoming blocked, leading to the failure of the entire nephrostomy tube 810. Furthermore, the fluid may contain large aggregates, such as blood clots. As the blood clots adhere to the surface of the tube's front section 814 and move along the drainage groove 8106 towards the drainage inlet 8101 under the suction at the drainage inlet 8101, the blood clots may be separated into smaller pieces by the partition wall 8142, thus reducing the probability of blood clots blocking the drainage inlet 8101.

[0211] It is understood that the multiple drainage inlets 8101 can be arranged on the same plane, or the multiple drainage inlets 8101 can be arranged in a non-planar manner. The upper and lower ends of the multiple drainage channels 8106 can be arranged flush, or the upper and lower ends of the multiple drainage channels 8106 can be arranged at different heights to reduce the probability of the drainage channels 8106 being blocked.

[0212] Furthermore, the drainage groove 8106 of the nephrostomy tube 810 is arranged close to the starting end 8111 of the nephrostomy tube 810, and at least a portion of the nephrostomy tube 810 is configured to extend outward from the starting end 8111. For example, in this embodiment, a structure resembling a pig's tail is formed at the starting end 8111 of the nephrostomy tube 810. During the insertion of the nephrostomy tube 810, the curved section of the nephrostomy tube 810 is guided into a straight line along the guide. After the guide wire or other guide is removed, the previously curved section automatically curls back into a curved shape, that is, it returns to its original shape. In this way, the nephrostomy tube 810 itself can have a certain fixing effect, so that it will not easily fall out of the user's body. In addition, due to the curved arrangement of the nephrostomy tube 810, the stimulation to the user inside the body is reduced, which is conducive to the user wearing the nephrostomy tube 810 for a longer period of time.

[0213] Furthermore, the drainage channel 8106 can be designed with different lengths so that different drainage inlets 8101 are located in different positions. In this embodiment, the longest drainage channel 8203 is arranged on the outside of the curved portion of the nephrostomy tube 810. On the one hand, this maximizes the drainage function of the drainage channel 8106; on the other hand, the drainage channel 8106 itself bends along with the curvature of the nephrostomy tube 810, reducing the chance of blockage at this location.

[0214] It is understandable that the nephrostomy tube 810 could be implemented as a straight tube, see attached figure. Figure 18 As shown in Figure 19, the drainage inlet 8101 is arranged in a stepped shape to help reduce the occurrence of blockages.

[0215] Reference Appendix Figure 25 To be continued Figure 26B As shown, a fixed nephrostomy tube device with an external receiving component 830 according to another preferred embodiment of the present invention is illustrated.

[0216] In this embodiment, the first connector 841 of the connecting unit 840 is detachably screwed to the second connector 842. The first connector 841 is fixedly connected to the second connector 842 by rotating the second connector 842, and the first connector 841 and the second connector 842 are tightly connected by the threaded arrangement of the two.

[0217] Referring to Figure 12, a fixed nephrostomy tube device with an external receiving component 830 according to another preferred embodiment of the present invention is illustrated.

[0218] In this embodiment, the external receiving component 830 is implemented as a tubing, such as a transmission tube or a connecting tube. The first connecting component 841 is disposed on the tube fixing portion 821 of the fixing unit 820 and is arranged around the nephrostomy tube 810, that is, around the fixing opening 8201 of the tube fixing portion 821. The second connecting component 842 is disposed on the external receiving component 830 and may be integrally formed with the external receiving component 830. In other words, the nephrostomy tube 810 can be directly connected to the tube fixing portion 821 of the fixing unit 820 via the connecting unit 840. Of course, it is understood that the nephrostomy tube 810 can also be connected to the body fixing portion 822 of the fixing unit 820.

[0219] Reference Appendix Figure 28 To be continued Figure 30B As shown, a fixed nephrostomy tube device with an external receiving component 830 according to another preferred embodiment of the present invention is illustrated.

[0220] Specifically, the fixing unit 820 includes a tube fixing part 821 and a body fixing part 822, wherein the tube fixing part 821 is used to fix the nephrostomy tube 810, and the body fixing part 822 is adapted to be fixed to the body surface of the user. The tube fixing part 821 is connected to the body fixing part 822 so as to be fixed by the body fixing part 822.

[0221] Since the nephrostomy tube 810 is fixedly installed on the tube fixing part 821, the tube fixing part 821 is fixedly installed on the body fixing part 822, and the body fixing part 822 is fixed to the body surface of the user, when the nephrostomy tube 810 is pulled by an external force, the tube fixing part 821 bears most of the force from the nephrostomy tube 810, and the body fixing part 822 further bears most of the force from the tube fixing part 821, thereby dispersing the pulling force to the body surface part of the user to which the body fixing part 822 is attached.

[0222] In this way, the probability of the nephrostomy tube 810 being pulled and causing damage to the stoma is greatly reduced. On the one hand, the nephrostomy tube 810 can be safely fixed in the fixing unit 820. On the other hand, the activity restrictions on the user during the activity process are also lifted to a certain extent, and the restrictions on the range of motion and activity are reduced.

[0223] In addition, the body fixing part 822 is arranged around the tube fixing part 821, and when the nephrostomy tube 810 fixing unit 820 is installed on the user, the nephrostomy tube 810 fixing unit 820 can close the stoma to prevent the fluid overflowing through the stoma from continuing to overflow outward, thereby reducing the chance of emitting odor.

[0224] Furthermore, the fixation unit 820 has a retention channel 82110, into which the nephrostomy tube 810 is adapted to be inserted and retained. The size of the retention channel 82110 is adjustable. When the nephrostomy tube 810 needs to be removed from the fixation unit 820, the retention channel 82110 can be adjusted to a larger size; when the nephrostomy tube 810 needs to be removed from the fixation unit 820, the retention channel 82110 can be adjusted to a smaller size.

[0225] It is worth mentioning that, in this embodiment, the nephrostomy tube 810 is implemented as a flexible tube, which may be made of materials such as rubber or silicone, to reduce discomfort for the user. Those skilled in the art will understand that the manufacturing material of the nephrostomy tube 810 can be selected according to needs; this is merely an example and does not limit the invention. Of course, it is understood that the nephrostomy tube 810 can also be implemented as a tube made of a more rigid material, selected according to actual needs.

[0226] After the nephrostomy tube 810 is inserted into the retaining channel 82110 of the fixing unit 820, the retaining channel 82110 is adjusted to narrow, and the fixing unit 820 squeezes the nephrostomy tube 810 to deform, thereby holding the nephrostomy tube 810 tightly. The nephrostomy tube 810 has the drainage channel 8103, the drainage inlet 8101, and the drainage outlet 8102, which are respectively connected to the two ends of the drainage channel 8103.

[0227] In this embodiment, the nephrostomy tube 810 is fixed to the fixing unit 820 by squeezing it, while simultaneously maintaining the drainage channel 8103 of the nephrostomy tube 810 in a conductive state. In other words, the nephrostomy tube 810, made of flexible material, can maintain normal drainage function after being fixed.

[0228] In detail, the tube fixing part 821 of the fixing unit 820 includes a force-applying component 8211 and a deformable member 8212, wherein the force-applying component 8211 is arranged on opposite sides of the deformable member 8212 to deform the deformable member 8212 by relative compression, thereby changing the size of the retaining channel 82110 formed by the deformable member 8212, and thus fixing the nephrostomy tube 810 passing through the retaining channel 82110 formed by the deformable member 8212.

[0229] The nephrostomy tube 810 passes through the deformable member 8212 in the axial direction. The force application component 8211 is configured to apply a compressive force to the deformable member 8212 in the axial direction, so that the deformable member 8212 deforms in the circumferential direction, thereby changing the size of the retaining channel 82110.

[0230] More specifically, the force-applying component 8211 includes a fixed support 82111, a movable member 82112, and has a retaining channel 82110 and a gap 821100. The retaining channel 82110 is through-dwelling, and the gap 821100 communicates with the retaining channel 82110 and extends the radial space of the retaining channel 82110 in the radial direction. The fixed support 82111 is adapted to be connected to the patch for fixation, the movable member 82112 is adapted to be movably connected to the fixed support 82111, and the gap 821100 is formed between the movable member 82112 and the fixed support 82111. When the movable member 82112 is moved toward the fixed support 82111, the gap 821100 is reduced.

[0231] The deformable member 8212 is accommodated in the gap 821100, and when the movable member 82112 is moved toward the fixed support 82111, the deformable member 8212 can be compressed by the relatively moving movable member 82112 and the fixed support 82111 to deform in the radial direction.

[0232] In this embodiment, the retaining channel 82110 of the deformable member 8212 is formed at an intermediate position of the deformable member 8212, which is defined as the inner side of the deformable member 8212. Correspondingly, the outer side of the deformable member 8212 is arranged on the force-applying component 8211. When the deformable member 8212 is squeezed by the fixed support seat 82111 and the movable member 82112 of the force-applying component 8211, the force-applying component 8211 restricts the deformable member 8212 from deforming outward, thereby ensuring that the deformable member 8212 will deform inward after being squeezed to a certain extent, so as to change the size of the retaining channel 82110.

[0233] In other words, the deformable member 8212 is configured to be mounted on the force-applying component 8211 and is limited on the outside to allow inward deformation.

[0234] Furthermore, the movable member 82112 includes a pressing head 821121 and a locking housing 821122. The pressing head 821121 is disposed within the locking housing 821122 and located inside the locking housing 821122. The pressing head 821121 forms at least a portion of the through-hole retaining channel 82110 inside the pressing head 821121. A receiving cavity and a receiving cavity opening communicating with the receiving cavity are formed between the pressing head 821121 and the locking housing 821122.

[0235] The fixed support 82111 includes a bottom support 821111 and a support housing 821112, the support housing 821112 being disposed on the bottom support 821111 and together forming at least another portion of the retaining channel 82110. The support housing 821112 is configured to extend upward from the bottom support 821111.

[0236] When the movable member 82112 is installed on the fixed support base 82111, the movable member 82112 is adapted to be installed from top to bottom from one side of the support housing 821112, and the support housing 821112 of the fixed support base 82111 is adapted to be inserted through the cavity opening of the cavity into the cavity formed between the pressing head 821121 and the locking housing 821122 of the movable member 82112.

[0237] The support housing 821112 forms an inwardly convex protrusion 821113, at which point the cross-section of the retaining channel 82110 is reduced to support the deformable member 8212, and the gap 821100 is formed between the extrusion head 821121 of the movable member 82112 and the protrusion 821113 of the support housing 821112. When the deformable member 8212 is installed in the gap 821100 of the force-applying assembly 8211, the extrusion head 821121 of the movable member 82112 and the protrusion 821113 of the fixed support 82111 on the support housing 821112 restrict the up-and-down movement of the deformable member 8212 in the axial direction, and the support housing 821112 of the fixed support 82111 on the outside of the deformable member 8212 restricts the degree of outward deformation of the deformable member 8212.

[0238] When the movable member 82112 is moved such that the pressing head 821121 moves toward the protrusion 821113 of the support housing 821112, the locking housing 821122 also moves synchronously toward the bottom support 821111, and at this time the locking housing 821122 is located outside the support housing 821112 of the fixed support base 82111, and the pressing head 821121 is located inside the support housing 821112 of the fixed support base 82111. The locking housing 821122 is fixably connected to an outer wall of the support housing 821112 of the fixed support base 82111.

[0239] In this embodiment, the locking housing 821122 of the movable member 82112 is configured to be screwed to the support housing 821112 of the fixed support base 82111. Optionally, the locking housing 821122 of the movable member 82112 may also be the support housing 821112 that is snapped onto the fixed support base 82111.

[0240] When the deformable member 8212 of the fixing unit 820 is in an initial state, the nephrostomy tube 810 can easily pass through the retention channel 82110 of the fixing unit 820. After the movable member 82112 of the force application assembly 8211 of the fixing unit 820 or the fixing support 82111 is operated to generate relative movement, the extrusion head 821121 of the movable member 82112 is pushed toward the protrusion 821113 of the support housing 821112 of the fixing support 82111. The deformable member 8212 is compressed in the axial direction, so that the extruded portion overflows in the radial direction to reduce the cross-sectional area of ​​the retention channel 82110, thereby enabling the nephrostomy tube 810 to be retained in the retention channel 82110 of the deformable member 8212. The friction between the nephrostomy tube 810 and the deformable member 8212 increases, locking the nephrostomy tube 810 to the deformable member 8212 of the fixing unit 820 at the fixed position. Simultaneously, the locking housing 821122 of the movable member 82112 moves along the supporting housing 821112 of the fixed support base 82111. When the movable member 82112 or the fixed support base 82111 stops moving relative to each other, the movable member 82112 is automatically fixed to the fixed support base 82111.

[0241] In the manner described above, the force-applying component 8211 of the fixing unit 820 can lock a flexible nephrostomy tube 810.

[0242] Furthermore, the deformable member 8212 can deform inward uniformly under the compression of the extrusion head 821121 of the movable member 82112 and the compression of the support shell 821112 of the fixed support seat 82111, so as to generate uniform extrusion force around the nephrostomy tube 810 and below the nephrostomy tube 810, thereby maintaining the conductivity of the nephrostomy tube 810 as much as possible while holding the nephrostomy tube 810 tightly, and avoiding the nephrostomy tube 810 being completely blocked at this position due to uneven force application.

[0243] Optionally, the deformable member 8212 is implemented as a symmetrical structure, an axisymmetric structure, or a centrosymmetric structure. The extrusion head 821121 of the movable member 82112 is implemented as a symmetrical structure, an axisymmetric structure, or a centrosymmetric structure. The protrusion 821113 of the support housing 821112 of the fixed support base 82111 is implemented as a symmetrical structure, an axisymmetric structure, or a centrosymmetric structure. The cross-section of the retaining channel 82110 formed by the deformable member 8212 is set to be circular, and the outer cross-section of the nephrostomy tube 810 is set to be circular.

[0244] When the fixed position of the nephrostomy tube 810 needs to be adjusted, for example, if the nephrostomy tube 810 is inserted too deeply for the current user, the operator can move the movable member 82112 away from the fixed support 82111. The force applied by the force-applying component 8211 of the fixing unit 820 to the deformable member 8212 is reduced, so the deformable member 8212 can automatically return to its initial state under elastic action. The retaining channel 82110 expands so that the nephrostomy tube 810 can be moved forward or backward. After the fixed position of the nephrostomy tube 810 is adjusted, the fixing unit 820 can be readjusted to fix the nephrostomy tube 810. In this way, the fixing unit 820 realizes the transformation between the restrained state and the open state, and the nephrostomy tube 810 also realizes the transformation between the restrained state and the movable state. Further, in this embodiment, the deformable member 8212 is a ring-like structure. In detail, the deformable member 8212 has a top surface 82121 and a bottom surface 82122, the top surface 82121 and the bottom surface 82122 are arranged opposite to each other and the top surface 82121 is arranged toward the extrusion head 821121 of the movable member 82112, and the bottom surface 82122 is arranged toward the protrusion 821113 of the support housing 821112 of the fixed support base 82111.

[0245] The top surface 82121 and the bottom surface 82122 are respectively configured to be raised, and the longitudinal section of the deformable member 8212 may be prismatic to allow for greater deformation within the same volume.

[0246] It is worth noting that during the deformation process of the deformable member 8212, the drainage channel 8103 of the nephrostomy tube 810 can be reduced to a certain extent, and the degree of reduction is controllable. Furthermore, the drainage channel 8103 can even be closed by the fixing unit 820. In other words, when the operator wishes to stop drainage from the nephrostomy tube 810, the drainage channel 8103 of the nephrostomy tube 810 can also be closed by the fixing unit 820.

[0247] Furthermore, in this embodiment, the deformable member 8212 is a solid elastic member. Due to the compression of the raised top surface 82121 and the raised bottom surface 82122, the deformable member 8212 is flattened as a whole, and due to the limitation of the outer force-applying component 8211, the deformable member 8212 is squeezed inward to restrain the nephrostomy tube 810.

[0248] Optionally, in another embodiment of the invention, the deformable member 8212 is implemented as a hollow air bladder 813 filled with gas. When the deformable member 8212 is compressed, it is flattened to increase its cross-sectional area, thereby constricting the nephrostomy tube 810. When the compressive force applied to the deformable member 8212 by the force-applying component 8211 is reduced, the deformable member 8212 rapidly recovers under the action of gas to release the nephrostomy tube 810.

[0249] Reference Appendix Figure 31A and Figure 31B As shown, the fixable nephrostomy tube device according to another preferred embodiment of the present invention is illustrated.

[0250] The main difference between this embodiment and the above embodiments lies in the fixing unit 820. In the above embodiments, the fixing support 82111 of the force-applying component 8211 of the tube fixing part 821 of the fixing unit 820 is screwed to the movable member 82112.

[0251] In this embodiment, the movable member 82112 is detachably snapped onto the support housing 821112 of the fixed support base 82111.

[0252] In detail, the movable member 82112 includes the pressing head 821121, the locking housing 821122, and a through-hole. The movable member 82112 is annular and has a U-shaped cross-section at at least one location. The end of the locking housing 821122 away from the fixed support 82111 is connected to the pressing head 821121, and the end of the locking housing 821122 near the fixed support 82111 has a recess for engaging with a protrusion 821113 formed on the bottom support 821111 of the fixed support 821111. It is understood that the positions of the recess and protrusion 821113 for engaging are illustrative and can be arranged according to needs by those skilled in the art.

[0253] Reference Appendix Figures 32A to 32B As shown, the fixable nephrostomy tube device according to another preferred embodiment of the present invention is illustrated.

[0254] The main difference between this embodiment and the previous embodiment lies in the connection method between the tube fixing part 821 and the body fixing part 822 of the fixing unit 820. In the previous embodiment, the tube fixing part 821 is fixedly connected to the body fixing part 822 through the fixing support seat 82111 of the force application component 8211.

[0255] In this embodiment, the tube fixing part 821 is detachably installed on the body fixing part 822, so that the body fixing part 822 can be used alone, or the body fixing part 822 and the tube fixing part 821 can be installed separately.

[0256] In detail, the fixed support 82111 of the tube fixing part 821 includes the bottom support 821111 and the support housing 821112. The support housing 821112 extends outward from the bottom support 821111. The bottom support 821111 is adapted to be connected to the body fixing part 822, and the support housing 821112 is adapted to be connected to the movable member 82112.

[0257] In this embodiment, the bottom support 821111 of the fixing support seat 82111 of the tube fixing part 821 is snapped into the body fixing part 822. The body fixing part 822 can protrude outward 821113 to form a platform for snapping into the bottom support 821111 of the fixing support seat 82111.

[0258] Therefore, during the installation of the fixable nephrostomy tube 810, the body fixation part 822 can be installed on the user first, then the nephrostomy tube 810 can be passed through the body fixation part 822 to be installed on the user, and finally the tube fixation part 821 can be installed on the body fixation part 822 and the nephrostomy tube 810 can be fixed in a suitable position.

[0260] In this embodiment, the first connector 841 of the connecting unit 840 is detachably screwed to the second connector 842. The first connector 841 is fixedly connected to the second connector 842 by rotating the second connector 842, and the threads of both connectors tightly connect the first connector 841 and the second connector 842. It is worth noting that the first connector 841 of the connecting unit 840 is also the movable member 82112 of the fixing unit 820.

[0261] Reference Appendix Figure 36 As shown, a fixed nephrostomy tube device with an external receiving component 830 according to another preferred embodiment of the present invention is illustrated.

The first connecting component 841 is disposed on the tube fixing portion 821 of the fixing unit 820 and is arranged around the nephrostomy tube 810, that is, around the fixing opening 8201 of the tube fixing portion 821. The second connecting component 842 is disposed on the external receiving component 830 and may be integrally formed with the external receiving component 830. In other words, the nephrostomy tube 810 can be directly connected to the tube fixing portion 821 of the fixing unit 820 via the connecting unit 840. Of course, it is understood that the nephrostomy tube 810 can also be connected to the body fixing portion 822 of the fixing unit 820.

[0263] In the above embodiments, the connection between the fixed support 82111 and the movable member 82112 of the force-applying component 8211 of the tube fixing portion 821 of the fixing unit 820 relies on a movable fixed connection on the outside of the fixed support 82111.
